Utah R. Civ. P. 29

The parties may modify the limits and procedures for disclosure and discovery by filing, before the close of standard discovery and after reaching the limits of standard discovery imposed by these rules, a stipulated statement that the extraordinary discovery is necessary and proportional under Rule 26(b)(2) and that each party has reviewed and approved a discovery budget. Stipulations extending the time for disclosure or discovery do not require a statement regarding proportionality or discovery budgets. Stipulations extending the time for or limits of disclosure or discovery require court approval only if the extension would interfere with a court order for completion of discovery or with the date of a hearing or trial.
